Each case is different and each injury affects a person differently.
Even if you and your friend both broke the same bone, your pain tolerance might be different. You might need surgery to correct the problem, whereas your neighbor didn’t. She might have worked for a messenger service as a “runner”, and her broken bone means she lost months from work. Your situation is probably different.
It’s important to know how your injury has affected your daily life, for example whether it impaired your ability to do your daily tasks like tying your shoelaces, taking a shower, making breakfast, going to the bathroom, holding groceries and similar activities.
Since everyone is different, and their injuries affect each person differently, the value for each case is different.
